General features of Sodium Carboxymethyl Cellulose

Food additives CMC is made by substiuting the hydroxy group (-OH) of cellulose with hydrophilic sodium carbozymethyl group (-CH2COONa) and then, adding water-solubility. It shows hydroscopic property like general water-soluble high molecules.
CMC is very stable chemically and it is harmless and non-poisonous to the human body. It is extensively used for viscosity increase, quantity increase, emulsification and dispersion, adhesion, colloid protection, and suspension.
CMC is a suitable compound for not only general industry, but also Encyclopedia of Food Additives, Korean Pharmacopoeia, and the Standards for Feed Additives for Fish-Farming. It is extensively used to various industries.
